From mid 1960s until late 1998 Cambodia was affected by protracted internal and regional conflicts that left a legacy of
landmines
,
cluster munitions
and other explosive remnants of war (
ERW
).

The north-west region of Cambodia bordering with Thailand was heavily affected by landmines and other ERW contamination. The Eastern region of the country was mainly affected by aerial bombardment as a result of the US-Vietnam war, leaving large areas contaminated by cluster munitions and other ERW. The post conflict has resulted in a large number of civilian casualties and effectively prohibited access to land and resources. The exact extent of contamination is not yet known, however, several hundred people fall victim to explosive objects every year. The vast majority of the total casualties are civilians and some 35 % of the civilian casualties are children.

Norwegian People's Aid's (NPA) Humanitarian Disarmament started in Cambodia in 1992- as NPAs first Humanitarian Disarmament effort. In January 2007, upon request by Cambodian Mine Action and Victim Assistance Authority (CMAA), NPA initiated the project called Empowering CMAA with the objective to assist the national authority and local operators in the process of analysing and using Humanitarian Disarmament data. NPA also has its own operations today and is working on implementing several projects, including an
MDD/EDD
training project.
